Why not m ake it proper Group 5 and let in 911's and twin cam Anglia's atc... or make it true to 66 (which could include some non FIA mods as ran in 66) but to have this mish mash of rules is illogical.
Why do you allow 2 litre Alfa's when that engine wasn't even produced until the mid 70's?
I see John Penfold's old car is on the mkt with car dealer Mike Abbas advertised as having FIA papers - that is a joke, the car is as far removed from an FIA Alfa as my L200 is....

Not taken personally, Simon. We do want constructive comment from all interested parties.
The main differences are brakes and suspensions. Discs are allowed all round but the benefit is not so great as the limiting factor is the grip (or non-grip!) of the Dunlop CR 65s that we run like the FIA cars. Too much brake makes the tyres slide. The main benefit is the ease of front to rear bias.
Suspension has to use the same design of the original (i.e. using a Cortina as an example, McPherson strut with TCAs and anti-roll bar at front and leaf springs with radius rods or coil springs with radius rods and 'A' bracket at the back0. We then allow additional locating rods such as tramp bars, watts linkages and panhard rods.
Gearboxes must use original design cases but 'dog' engagement and 5 speeds are allowed. hewland did a 5 speed box in period but only for 1.0 and 1.3 Anglias as they are not strong enough for Twin cam power outputs.
The 2 litre engine is allowed for Alfas and Cortinas under the same family regulation.
I can't comment on the ex John Penfold as I haven't seen the ad and it's not an HRSR matter. If the owner of the car registered to enter the App K classes at HRSR races it would have to produce, and comply with, the FIA papers as a 1600cc car.
